Given numbers are 934,816,820,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 934,816,820,390 is 1015556880.
Find LCM of 934,816,820,390 with Prime Factorization
| 2 | 934, 816, 820, 390 |
| 2 | 467, 408, 410, 195 |
| 3 | 467, 204, 205, 195 |
| 5 | 467, 68, 205, 65 |
| 467, 68, 41, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 467 x 68 x 41 x 13 = 1015556880
Therefore, the lowest common multiple of 934,816,820,390 is 1015556880.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
934 x 816 x 820 x 390 = 243733651200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
934 : 1, 2, 467, 934
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 934,816,820,390, is 2.
Now, the common factors can be found like this.
934:2x 467
816:2x 2x 2x 2x 3x 17
820:2x 2x 5x 41
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5 = 120
Therefore, the value for common factors is 120.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 243733651200/(2x120)
LCM = 243733651200/240
LCM = 1015556880
Thus, we can understand that the LCM of 934,816,820,390 is 1015556880.
